*7
Diagram NOT accurately drawn
\(PRS\) and \(TWY\) are parallel straight lines.
\(QRWZ\) is a straight line.
Work out the value of \(x\).
Give reasons for your answer. (3)
| Answer | Mark | Notes |
|---|---|---|
| 54 with reasons | 3 | M1 for angle \(RWY\) or angle \(TWZ = 180 - 126\) (= 54) or angle \(TWR\) or angle \(WRS = 126\) (may be marked on diagram) A1 for 54 C1 for appropriate reasons for method shown eg. Angles on a straight line add up to 180 and Alternate angles are equal OR Corresponding angles are equal and Angles on a straight line add up to 180 OR Vertically opposite angles are equal and Allied angles / Co-interior angles add up to 180 OR Angles at a point add up to 360 with other reasons as above. |
